The Crystal Billet Box by David Regal standard size
This is a gimmicked box that has been precision-crafted from thick acrylic that enables a performer to switch a group of billets, force an item, make something appear, make something vanish, and can even be used as a prediction chest.
It comes ready to go, along with a few extras that give the performer some options that further increase its utility.
Watch the video - it is the opposite of a "fancy ad." There's no music or flashy editing. It simply shows you what the Crystal Billet Box is. The box's workings are not discussed in the video but those of you who figure out what's going on will, we think, be even more eager to get one.
